That's such a tough call. I'm pretty sure a rehab vet would say no, don't do it and that is a great question for one. Our personal feeling is that we don't allow Wyatt Ray to play it. Here's why:

As we mention in the Tripawds e-books , when Jerry lost his leg, we didn't know anything about life on three legs, we just wanted him to live life and enjoy the things he always did knowing he was on borrowed time. So we continued playing frisbee, one of his favorite games. We didn't like to see him jump so high on one front leg, we knew it couldn't be that good for him, so we did our best to keep tossing it low, and played with a soft frisbee, not a hard one, which tended to catch more air. However, it wasn't long before there was just one moment when he landed wrong and he did something to his rear knee. He hobbled and was in horrible pain and we felt awful. His vet suspected an ACL tear.  It took acupuncture to help the pain go away and eventually he got better, but we learned our lesson: those three legs are just too precious t us to take chances like that.

A recent Colorado State vet study found that statistically, whether a dog is a front or rear leg amp, odds are they could have some type of chronic pain and/or injury to their rear limb as time progresses. Maybe we're paranoid but after hearing that, we've decided that we'll do all we can to avoid future incidents, including banning high impact activities like that.

Now, there are dogs like Kess the Border Collie and Matey the frisbee dog who still play Frisbee, catch air and do all kinds of crazy stuff. They're having a ball and at some point I'd love to hear how their people practice injury prevention techniques, just haven't had a chance to do that. Seeing them play is a joy!

So, what do you do when you have a young, active Tripawd? One thing we've learned from rehab vets is that tiring a dog's mind more than his body is more rewarding for the dog and the human, now and later. Games like K9 Nosework and scent games, obedience games and the like really get a dog's brain going and in the long run do much more for the dog as age sets in; as s/he ages and their body isn't physically capable of crazy athletics, being able to stimulate their brain helps keep them mentally alert and keep dementia away. By training him in brain games now, you'll be so glad you did when he's an old dog.

Again, this is just our gut feeling. We are not rehab vets so this is something I would love to address with one soon!
